HYDRAULIC DUPLEX MOTOR.

Specification of Letters Patent.

Patented July 30, 1912.

Application filed January 15, 1906. Serial No. 296,183.

To all whom it may concern:

Be it known that I, ORESTE ANGELINI, subject of the King of Italy, residing at Rome, Italy, have invented new and useful Improvements in Hydraulic Duplex Motors, of which the following is a specification.

This invention has for its object to improve the utilization of the driving power that can be obtained from water falls or other liquids or fluids under pressure.

According to this invention the liquid is caused to pass through a branched tube or conduit the interior of which is in communication with the underside of a cylinder, the piston of which is connected by a rod to the crank shaft of the motor.

Figure 1 is a View of the hydraulic motor connected to a Pelton wheel. Fig. 2 is a plan view of the valve disk. Fig. 3 is a sectional elevation, partly broken away, of the device. Fig. 4 is an elevation of the lower portion of Fig. 3, at right angles to that of the latter.

In Fig. l of the accompanying drawing a is the conduit for the liquid, Z) are the branch pipes admitting liquid to the cylinder c, and e is the piston, d being the rod driving the crank secured to the shaft of the motor. v

The base or end of the motor conduit, whence the liquid escapes, is provided with a valve for varying or rendering intermittent the discharge of the liquid flowing through the motor, and may, for instance, be provided with a disk with openings y (Fig. 2) of trapezoidal section ar- On the said ranged in radial direction. disk z' is mounted, rotating about the center, a movable disk h., provided with as many radial openings of the same size as those of the under disk. The movable disk k is controlled by a lever driven by an eccentric secured to the shaft of the motor and by its movements it renders the escape or discharge intermittent or reduces or varies it. When the liquid escapes freely the piston eof the motor is forced downward by the atmospheric pressure which overcomes the dynamic pressure of the escaping liquid. which in its turn falls upon the vanes m on a Pelton wheel -p arranged below, while, when owing to the action of the movable disk -h, the dis charge is suddenly interrupted or reduced,

the pressure taking place in the interior of the cylinder o-, owing to the so-called rain action forces the piston e upward. The shaft 1?. of the Pelton wheel is connected by means of pulley Z on shaft a, pulley f on the crank shaft g and a belt or chain -g to the shaft 9 of the piston motor, so that it forms a fly wheel or assistant motor for the same.

I claim 1. An apparatus of the character described comprising av power crank-shaft, an open-ended cylinder, a piston operating in the cylinder, a liquid conduit with which the underside of the open-ended cylinder communicates, a water-wheel, belted connection between the water-wheel and the said crankshaft, and means for opening and closing the discharge orifices of the conduit for regulating the escape of the liquid, substantially as described.

2. A hydraulic motor of the kind described comprising a liquid down-conduit, a cylinder in free communication at its lower end with the conduit and at its upper end with the atmosphere, a piston in said cylinder, and a shaft driven by the piston, an intermittently-operated valve adapted to open and close the opening of the conduit below the cylinder and a water wheel driven by the escaping liquid, belted connection between the water-wheel and the shaft driven by the piston, said water-wheel acting as an auxiliary motor substantially as'described.

3. The combination of a liquid conduit, a cylinder in free communication at its lower end with said conduit and at its upper end with the atmosphere, a piston in said cylinder, a crankshaft driven by the piston, awater wheel, belted connections between the water wheel and the crank-shaft, a station ary disk having openings, a rotatable disk having openings adapted to register with the openings in the stationary disk, and all 'said openings adapted to communicate with the said conduit, and means for rotating the rotatable disk.

In testimony whereof I have si ed my name to this specification in the presence of two subscribing witnesses.
